WATER-MOTOR.

Application filed. May 8, 1915.

To all whom it may concern:

Be it known that I, BENJAMIN F. FOWLER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Water- Motors, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a water motor, and has for its principal object the production of a simple and eiiicient improvement over my prior Patent No. 883,105, issued March 24, 1908.

Another ob ect of this invention is the production of a water motor having a plurality of pumps used in connection therewith, these pumps being so constructed as to cause water to be drawn thereinto and then be expelled through desired pipes by a direct pressure of the pumps.

Another object of this invention is the production of a water motor in which the gate valves are provided with simple and efficient operating means for intermittently permitting the flow of water through the flume into the buckets for reciprocating the buckets and operating the pumps.

Another object of this invention is the production 01 a device of the character set forth which is simplified in construction and, therefore, more efficient in operation and less expensive in production With these and other objects in view, this invention consists of certain novel combi nations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of the water motor as constructed'in accordance with this invention. Fig. 2 is a front elevation of the water motor. Fig. 3 is a top plan view of the water motor. Fig. 4 is a central longitudinal section through the device. Fig. 5 is a fragmentary sectional view through a portion of the device, showing one of the pump motors in section. Fig. 6 is a detailed perspective view of one of the buckets. Fig. 7 is a fragmentary sectional view through a portion of the motor, illustrating the manner in which the buckets are supported. Fig. 8 is a fragmentary sectional view, illustrating the manner in which the gate valves engage the strips carried for forming a tight closure. Fig. 9 is a sectional view through a portion of th y l-Wi Specification of Letters Patent.

Serial No. 26,878.

illustrating the manner in which the operating means of the gate valves are actuated. Fig. 10 is a section taken on the line 1010 of Fig. 4. Fig. 11 is a section taken on the line 1111 of Fig. 2. Fig. 12 is a section taken on the line 1212 of Fig. 2.

Referring to the accompanying drawings by numerals, it will be seen that the framework of the water motor comprises the vertical supporting beams 1, which carry at their upper ends the side boards 2 of the flume. The horizontal boards 8 are carried adjacent the upper ends of the supporting beams 1 so as to support the bottom 1 of the flume. The longitudinal bracing beam 5 is carried adjacent the lower ends of the supporting beams 1, and a number of these beams 1 have the transverse boards 6 fitting beneath the longitudinal beams 5 extending transversely across the frame, so as to prevent the lower portions of the frame from spreading when in operation. It will further be seen that the top boards 7 extend around the upper edges of the sides 2 of the fiume. It will be noted by referring particularly to Fig. 1 that the bottom 4 of the fiume terminates at a distance from the forward end of the frame of the water motor, so as to leave an open portion through which the water passing through the flume may fall toward the lower portions of the frame. When this frame is in position the rear end of the bottom 4 of the flume will fit upon the bed ofv a small stream, so as to cause the water to flow through the flume. The supporting beams 1 however, will rest upon the surface lower than the bed of the stream, which is even or substantially even, with the bottom 4:. Therefore, the water passing through the sluice will fall over the forward end of the bottom 4; to pass to the lower level which is even with the lower ends of the supporting beams 1.

, Each bucket 8 has its upper portions open, and has the side thereof braced by the intermediate end strip 9. The supporting lever for the buckets 8 comprises a pair of side sections 10 which are held in parallel spaced relation by means of the rungs 11. The forward ends of these sections 10 of the lever are pivotally secured by means of the rivets or bolts 12 to the bucket, as clearly shown in Fig. 6. The rear ends of these sections 10 are pivotally mounted upon a horizontally extending rod 13 carried by a pair of the vertical supporting beams 1, so as to allow these sections to freely pivot when the device is in operation. A walking beam 14 is provided at its forward end with the yokes 15, which are held in engagement therewith by means of the rivets 16. These yokes' 15 extend so as to embrace the side portions of the bucket 8, whereby the bolts 17 which pass through the forward ends of the yokes 15 for pivotally securing the same in engagement with the bucket 8, will also pass through the depending ends 9 of the brace strip 9. The rear end of each walking beam 14 is pro vided with the side plates 18 which are fixed thereon for the purpose of engaging the pump mechanism, to be hereinafter fully described. A horizontal rod 19 also passes through the same vertical beams which support the rod 13. The rod 19 passes through the walking beams adjacent their rear ends for pivotally supporting the walking beams intermediate their ends, whereby when the forward end of the beams are swung, the rear ends will also be swung, although the movement thereof will not be as great, as the forward ends. In order to reciprocate the buckets 8, the brackets 20 are fixedly carried in alinement with each other by the upper portions of the top boards 7, as clearly shown in Figs. 1 and 3. A supporting board 21 is fixedly mounted by the securing members 22 upon the upper portions of these brackets 20, and is provided adjacent its central portion with the alined slots 23. The journal brackets 24 are carried in pairs adjacent the side portions of the slots 23 for the purpose of receiving the ends of the journals 25 upon which the sheaves 26 are rotatably mounted. From this description it will be seen that the sheaves will be carried in alinement with each other so as to freely rotate at a distance within the upper portions of the frame of the water motor. The vertical tubes 27 are soldered or otherwise secured upon the central portions of the brace strips 9 of the bucket 8 for the purpose of receiving the ends of the cable 28. The ends of the cable 28 are passed downwardly into the tubes 27 so as to allow the set screws 29 carried by the collars 30 upon the tubes 27 to pass thereinto and bind upon the cable 28 adjacent its end portions for retaining the cable in an operative position. It will be noted by referring particularly to Fi 2, that the length of th'ecable is such that when one bucket is raised the other bucket is in its lowest posi tion and, therefore, it is necessary for the buckets to move in unison, while the cable 28 will pass around and over the sheave 26 when the water motor is in operation. The forward end of each bucket 8 is also provided with a supporting strip 31, having the leaves 32 fixed thereon adjacent its end portions for receiving the pin 33. This pin 33 passes through the sleeves 34 fixedly secured to the pivoted flap 35 which forms an end for the bucket 8. A strip 36 having a weight 37 formed upon its inner end, is fixedly mounted by means of the rivet or other securing means 38, upon the flap end, so that the earrying of the weight 37 oif center will normally urge the flap end 35 toward an open position for allowing the water carried within the bucket to be emptied therefrom, inasmuch as the flap 35 will be open, as shown in full lines in Fig. 4.

A locking bar 39 is pivotally mounted, as shown at 40, upon the flap end of each bucket 8 and has a central depending lip 41 formed intermediate its ends for the purpose of engaging the slotted plate 42 fixedly mounted upon the lower surface of the bucket 8. Therefore, when this lip 41 passes into the slot of the plate 42, the flap end 35 of the bucket 8 will be releasably held in a closed position. The free end of the locking bar 39 passes through the guide bracket 43, whereby the locking bar will be held in snug engagement with the end ilap 35 throughout its entire length with the exception of its outer end portion. In order to actuate this locking bar 39 it will be seen that the forward supporting beams 1 are provided with the clips 44 in which there are formed slots 45 for the reception of the set screws 46. These clips 44 are provided with the angularly extending portions 47 which are adapted to be engaged by the outer end of the locking bar 39. \Vhen the bucket moves upwardly the flap end will be extending toward an open position. The guide strand 48 is fixedly secured to the forward side 2 of the flume so as to extend for a considerable distance therebelow. The lower end of the strand is bent outwardly, whereby when the bucket is raised the flap end will pass behind the strand, and will, therefore, be moved to a closed position for closing the forward end of the bucket. \Vhile the flap end is in this closed position, the free end of the locking bar 39 will come into engagement with the upper clip 44, as shown in Fig. 2, whereby the lip 41 will be passed through the slotted plate 42, thereby locking the flap end 35 in a closed position. \Vhen the bucket is filled it will move downwardly until the flap end disengages the strand 48, at which time the free end of the locking bar 39 will engage the lower clip 44, thereby swinging the locking bar so as to cause the lip 41 to disengage the slotted plate 42, whereby the force of the water together with the urging force of the weight 37, will swing the flap end to an open position for allowing the water to escape from the interior of the bucket. It will be noted that the clips 44 are slotted so as to allow the same to be adjusted slightly for the purpose of determining the exact predetermined time when the bar 39 will lock the fiap in a closed position, or when it will release the flap end so as to allow the same to swing to an open position. The longitudinal beams 5 are adapted to carry the cradle which comprises a U-shaped strip 49 having slots 50 formed therein, through which the set screws 51 pass for retaining the cradle in aset position. A buffer strip 52 is carried in the lower portions of the Ushaped strip 49, and upon this buffer strip'52, the bucket is adapted to rest when in a lowered position. It will be seen that by the adjustment of the screws 51 the exact stroke of the pump may be determined, as it may be slightly in creased or decreased by the adjustment of this cradle. In order to intermittently supply the two buckets with water a central rib 53 is fixedly mounted upon the bottom 4, and extends beyond the forward end of the bottom so as to be carried by the forward side 2 of the flume. The transverse supporting strip 54 is carried by the upper portions of the top strips or boards 7, so as to fixedly carry the plates 55 of the sleeves 56. The lifting levers of the gate valves 57 comprise a pair of sections 58 and 59. The

section 58 is U-shaped and passes through the sleeves 56 so as to have its forward ends provided with the retaining nuts 60, whereby the gate valve 57 will be fixedly retained in a set position upon the forward ends of the section 58. A packing strip 61 is carried adjacent each end of each gate valve 57 so as to form a tight closure when the gate valve adjacent each end of each gate 57 so as to form a tight closure when the gate valve 57 is in a closed position. Therefore, when the gate valve is in a closed position, the water within the flume will be prevented from running upon the particular side of the rib 53 adjacent which the particular gate valve is closed. The section 59 of the lifting lever of the gate valve 57 is also carried by the gate valve 57, being secured thereto in any suitable manner as indicated at 62. Each section 59 converges toward its forward end so as to pass around the cable, as clearly shown in Fig. 4. A lifting stop 63 is clamped upon the tube 27 by means of the bolt 64, and has the laterally extending cars 65 for the purpose of engaging the section 59 of the lifting lever of the gate valve when the particular bucket is raised. Therefore, by having these ears 65 engage the section 59 as the bucket is raised, the particular gate valve will also be raised when the bucket is in its highest position. The water within the flume will then pass down the side of the rib 53 into the bucket 8 until the bucket is filled, at which time the weight thereof will cause the same to move clownwardly, thus allowing the weight of the lifting lever formed in the sections 58 and 59 to swing the gate valve to a closed position for cutting off the flow of the water upon this particular side of the rib 53.

The pumps which are used in connection with this water motor are carried adjacent the rear ends of the flume. The L-shaped pipe 66 has a retaining plate 67 soldered thereon, for the purpose of allowing the retaining screws 68 to be passed therethrough for retaining this pipe in a set position. The T-shaped thimble 69 is threaded into engagement with the pipe 66, so that the passageway through the pipe 66 into the thimble 69 will be continuous. This thimble 69 is provided with a cap 70 for closing its upper portions and allowing access to the depending flap valve 71, which forms a channel for the passage of liquid or water in one direction after the water has passed through the thimble. This depending flap valve will allow the water to pass through the pipe 66 of the thimble 69, but will prevent its backing through the thimble and then through the pipe 66. A short pipe 72 is threaded into engagement with the thimble 69 and is fixedly secured, as by solder, to the pump cylinder 73. The pump head 7 4 is carried upon the stem 75, which depends for a considerable distance below the lower end of the cylinder 7 3. The lug 76 is carried by this stem and is mounted upon the pin 77, mounted in the slotted ends 78 of the plates 18 carried by the walking beam 14. Therefore, it will be seen that as the walking beam is rocked, the movement of the rear end thereof will cause the stems 75 to reciprocate the head 74 within the cylinder 73. A hood 79 is provided with a flange 80 fitting upon the gasket 81 mounted upon the retaining plate 82 of the pump cylinder 7 3. The retaining screws 83 may then be passed through the flange 80, the gasket 81, and. the plate 82 so as to engage the bottom 4 of the flume for fixedly retaining the hood 79 in its correct position above the upper end of the pump cylinder 7 3. The upper end of the pump cylinder is provided with a reduced opening 84 which is adapted to be closed by means of the horizontal flap valve 85. The upward movement of this valve 85 is limited by the abutment screw 86 which passes through the hood 79 and engages the rear portions of this flap valve 85. It will be seen that as the pump head 74 moves upwardly, it will force the water which is drawn into the pump cylinder 73 upwardly through the valve 85 and through the neck 87 of thehood 79 into the pipe 88, which is carried by the collar 89, in engagement with the neck 87. From this construction it will be seen that as the pump head moves downwardly within the pump cylinder 73, the suction thereof will cause the flap valve 85 to remain snugly upon this side for closing the opening 84, the suction, however, will cause the water passing through the flume to be sucked through the pipe 66 of the flap valve 71 so as to pass on through the thimble 69 and the short pipe 72, into the pump cylinder 73. When the pump head reaches its lowest position within the pump cylinder 73, the interior of the cylinder will be filled with water. Then upon the upward movement of the head 74, the force of the water will close the flap valve 71 and open the flap valve 85, whereby the direct pressure of the head moving upwardly as the walking beam is swung downwardly at its forward end, will cause the water to pass through the hood 79 and neck 87 into the pipe 88, so that the water may be carried or conveyed under pressure to any desired place. In order to allow the walking beams 1a to operate eflieiently without binding action either upon the buckets or the pumps, the vertical brace beams 90 are carried in parallel spaced relations, for fitting upon the side portions of the walking beams let, and are carried by the beams 3 and 6. These vertical brace beams may be braced intermediate their ends by means of the filler block 91,-which is retained in a set position by means of the bolts or rivets 92.

iVhen this device is in operation, it is set up so as to allow the rear end of the bottom 4: of the flume to extend,as above set forth, adjacent the lower surface or bed of the stream or sluiceway from which the water is adapted to be supplied to this water motor. The water from this stream will then pass between the sides 2 of the flume, passing over the upper portions of the pump members, which will be carried by the bottom of the tlume extending above the upper surface thereof, as clearly shown in Fig. 3. The

water will, of course, fill the pipes 66. At this time one of the buckets will be carried by the cradle in its lowest position, while the opposite bucket will be carried adjacent the upper portion of the frame, as shown in dotted lines in Fig. 4: and in full lines in Fig. 2. The upper bucket will have its flap end 35 closed, while the ears of the stop 63 will hold the section 59 in an elevated position, thus leaving the gate valve 57 open upon one side of the rib 53. The water within the flume will then pass beneath this gate valve, until the bucket which is carried ad acent the upper portion of theframe 1s filled. The weight of the water wlthin the bucket will then cause the bucket to move downwardly, thereby closing the gate valve and cutting off the flow of the water upon that particular side of the rib 53. The empty bucket will then be ascending, and through its ascension the strands 48 will engage the liap of this particular bucket, for swinging the flap to a closed position, at which time the locking bar of each bucket will lock the flap closed, so that when the gate valve upon this side of the rib 53 is raised the water may pass into the bucket without escaping. At this time the bucket which has been pre viously filled will be passing downwardly so that the locking bar w ll be engaged by one of the lower clips 44 for lifting the lip of the locking bar from engagement with the slotted plate, whereby the flap end may be swung to an open position for allowing the water to be emptied from the bucket. It will be seen that owing to the fact that the two buckets are connected together by means of the cable 28, the weight of the bucket filled with water will cause the empty bucket to be raised to an elevated position, so that it may be filled, and this reciprocating action will be continued as long as the stream of water is supplied to the iiume. This reciprocating action of the buckets will cause the rear ends of the walking beams let to be moved upwardly and downwardly, and, therefore, the pumps will be actuated, drawing the water into the pump cylinders 73, and thus upon the forward movement of the head within the pump cylinders, the water will be forced upwardly through the hood 79, the neck 87, and then through the conducting pipes 88 to any desired position or height, as the continued pivotal action of the walking beams will continue to force the water until any desired quantity has been produced, or until the water has been moved to any desired position. It is, of course, obvious that the supply of water may be very small or very great, according to the size of this motor.

From the foregoing description, it will be seen that a very eliicient water motor has been produced, which is operated by the flow of a small stream by the reciprocation of the buckets, whereby the pumps will be operated so as to suck or draw the water pass ing through the flume therein, for being expelled through a desired pipe or pipes to wherever it is necessary to convey the water.

It will be seen, of course, that by employing the levers 10 in connection with the beams 14, the buckets are held from tipping or dumping when reciprocating, and therefore, the only possible manner in which the water can be emptied from the buckets is by the releasing of the flap ends as above set forth.

In awater motor of the class described, the combination of a frame, pumps carried by said frame, walking beams pivotally mounted upon said frame and engaging said pumps, buckets pivotally mounted upon the forward ends of said walking beams, a rib carried by the upper portion of said frame, gate valves positioned upon each side of said rib, lifting levers pivotally mounted upon said frame and secured to said gate valves, the forward end of said lifting levers being positioned directly above said buckets, means connecting said buckets so as to carry one bucket in an elevated position while the opposite bucket is in a lowered position, the upward movement of one bucket being adapted to cause a direct upward pressure to be exerted upon the upper lifting lever whereby the gate valve may be open for allowing water to pass into said bucket, at which time the bucket will move downwardly so as to swing the walking beams for exerting a direct pressure upon the pumps.

14. In a water motor of the class described, the combination of a flume, pumps carried by said fiume, each pump comprising an i.- shaped pipe communicating with the interior of said fiume, a thimble carried upon said pipe and provided with a fiap valve, a short pipe carried by said thimble, a pump cylinder connected to said short pipe, a pump head having a stem extending therethrough, a hood carried above said cylinder, and provided with a flap valve, means for reciprocating said stem for causing said head to move within said pump cylinder, whereby the water passing upon the upper portions of said flume may be sucked into said pump cylinder from said pipes and thimble after which upward movement of the head will open said last mentioned flap valve and permit water to be forced to a desired position.

15. In a water motorof the class described, the combination of a flume, pumps carried upon said flume, each of said pumps comprising an EL-shaped pipe, a thimble carried upon said pipe and provided with a flap valve, a short pipe connected to said thimble, a pump cylinder connected to said short pipe, a hood fitting upon said pump cylinder and provided with a flap valve, a pump head positioned within said pump cylinder, stems connected to said heads, walking beams pivotally mounted upon said fiume and connected to said stems, said fiume being adapted to allow water to flow thereupon, buckets connected to the forward ends of said walking beams, means for supplying said buckets with water for reciprocating the same, whereby the walking beams will be reciprocated for reciprocating said stems, thereby causing the heads to first suck the water from the upper portions of said flume through said pipes and thimble into said cylinders, after which upward movement of the heads will cause the water to be forced from said cylinders and said hood to a de sired position.

In testimony whereof I hereunto aiiix my signature.
